How to call in sick while on holiday abroad:

If you fall ill while on holiday, you must see a doctor. There, you can get a sick note/certificate of incapacity to work. You must inform your employer immediately about how long you will be ill for and where you currently are. You also need to inform your health insurance company. You should submit the certificate of incapacity to work as soon as possible, but there is no deadline for this.

Important: if you become unable to work while on holiday and take sick leave, you can get the sick days back.

For example, if you were ill for two days and on sick leave, you will get two days of holiday back at the end of your holiday.
